Less acute, less than a modern cabinet SWR or David Eden, Fidler fairly neutral and what comes out of the amp unlike the equivalent in ampeg cabinet. Enough rock in general, may be effective but a little lightweight in the bass to dub for example.
I use a bass G & L, an H & Ketner distortion and good cables (important!)
I abm810 2 for 1 month is a bit difficult move, but a return to my twingo, I finally hear my BPS. I tried DIFFERENT MODELS (swr, ampeg, David Eden ...), this is the one I prfre, with a little hesitation to the ampeg ct.
